Intel · Pentium III · 1999 · 370
The Intel Pentium III 800 is a desktop processor with 1 core, released in 1999 at an MSRP of $408. It is part of the Pentium III lineup, using the Pentium III platform, and fits the 370 socket. Internally, it is built on the "Coppermine" architecture. It operates at a fixed 0.8 GHz. Intel manufactures the "Coppermine" silicon on a 180nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports SDRAM memory. With a TDP of 24W, the Pentium III 800 is an efficient chip suitable for modest cooling solutions. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB of L1 and 256KB of L2 cache. There is no L3 cache on this processor.
Coppermine. Available in 100 MHz (800E) and 133 MHz FSB (800EB) variants, and in both Slot 1 and Socket 370 form factors.
